The ST300 comes equipped with a Classic Series C22B humbucker in the bridge, and a Classic Series C22J pickup in the neck position, which are custom wound with vintage plain enamel wire that brings out the harmonically rich tone and sustain of the guitar. All Carvin humbuckers have 11 polepieces per coil, which eliminates dropoff when bending strings. Controls consist of a master volume and tone control and a 5-way pickup selector, which allows you to select any combination of pickups and doubles as a coil splitter for each pickup.
